Cryptarchia: Private Proof-of-Stake
Most proof-of-stake systems reveal who proposed each block, creating a target for censorship, bribery, and coercion. Logos solves this with Cryptarchia, a private proof-of-stake mechanism in which block proposers are selected through a private lottery and anonymised through Blend, a mixnet-based protocol. Validators take part in consensus without revealing their identity during block proposal — a privacy guarantee most blockchains cannot offer.
